Now we can override default cache key much easier, which allows us to eg. separate content for different languages when caching it.

eg. separate content for different languages when caching it.
What are the main changes in this PR?
When plugin is loaded, it generates default value for
WP_CACHE_KEY_SALT, if there is none defined. User is able to override our defaults (we set WPML language and multisite site ID if we can determine values for those).Why are we doing this? Any context or related work?
This fixes multiple cases where customer has encountered issues when using object-cache, as OC has eg. cached multiple languages with same keys, thus showing wrong content to wrong users.
Where should a reviewer start?
Manual testing steps?
So far what I've tried to do when testing this:
redis-cli keys '*'that keys now values_prefix, and if site is multisite or if WPML is installed and enabled, there is also base64-encoded prefix for cache keysScreenshots
